Tyne Diffuse Investigation and Mitigation Methods

The Coal Authority invites you to tender for a watercourses contribute towards the metal contamination and has been responsible for the failure of ecological status of South Tyne watercourses under the terms of the Water Framework Directive (WFD), therefore there is the need to identify and limit the impact from sources of metal contamination throughout the catchment.

Over the past four years, as part of the Water and Abandoned Metal Mines (WAMM) programme which is funded by Department for Environment, Food and Rural Affairs (Defra), The Coal Authority (CA), in partnership with the Environment Agency (EA), have implemented various mitigation methods at several locations across the catchment to reduce contaminated sediment from entering the watercourse.

To provide necessary services required to establish a programme of work which will identify areas of diffuse pollution that would benefit from 'green' engineering mitigation measures.

The design and installation of methods to reduce any water runoff, prevent the erosion of the former spoil heaps and stop the mobilisation of contaminated sediment from entering the watercourse, thereby improving water quality standards in the Tyne catchment and at the Port of Tyne.
